Hi there and thanks in advance.

I have a large symmetrical matrix stored in a text file. After load in R I would like to extract the same number of columns and rows (symmetrical submatrix) using their labels.

I have tried this code in order to extract columns, but R console gives me the "+" sign at the end of the code, pointing out incomplete command, so it is not working:

m<-read.table("C:/backup/symmetrical.csv")

n<-subset(m, select=c("X1", "X7", "X12", X15", "X22", "X26", "X31", "X34", "X39", "X44", "x51", "X58)

Therefore, I have no tried with row names yet.

Any suggestions? Sorry for the inconvenience. I have read some information about this but always have the same problem with "+" and I do not have any idea to follow.

Best,

AJ
